The Hope Slide, which took place on January 9, 1965, in British Columbia, stands as the largest landslide ever officially recorded in Canadian history. The catastrophic failure unleashed an estimated 47 million cubic meters of rock, mud, and pulverized stone down the face of Johnson Ridge, completely burying a section of Highway 3 under deep layers of debris. Despite the immense scale of the disaster, which buried the valley floor instantly, four passing motorists were caught in the path and tragically lost their lives.
